A. The wavelength of microwaves is greater than that of UV-rays.
B. The wavelength of IR rays is lesser than that of UV-rays.
C. The wavelength of microwaves is lesser than that of IR-rays.
D. Gamma rays have shortest wavelength in the Electromagnetic Spectrum.
Of the above statements
Answer & explanation
Correct answer: option 4
The wavelength order of the given types of waves are given below
Waves Wavelength Range (in meter)
Gamma rays IR-rays 10−14 −10−10
IR-rays 7 × 10−7 = 10−3
UV-rays 10−9 − 4 × 10−7
Microwave 10−4 − 100
Hence, statements (A) and (D) are correct.
